Solution Overview
Problem
Existing temperature adjustment devices, such as air conditioners and refrigeration systems, consume excessive energy due to inefficient compressor operation, and existing energy-saving techniques have not adequately addressed this issue.
Innovation Solution
A control device that includes intake and exhaust temperature sensors, along with a control signal output part, to manage compressor operation based on detected temperatures, stopping or reducing compressor speed when predetermined temperature conditions are met, and switching between cooling and heating modes to optimize energy use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the compressor operates continuously to maintain temperature adjustment function, then temperature control reliability is improved, but energy consumption increases
Solution Approach 1:
The control device implements periodic monitoring of intake and exhaust temperatures, comparing detected values against target temperatures at regular intervals. The compressor operates periodically based on these comparisons, switching between on and off states or varying speed levels according to whether the detected temperatures meet the target conditions, thereby reducing continuous operation and energy consumption while maintaining necessary temperature control
2Use of energy by moving object
If the compressor is stopped or reduced to low speed to save energy, then energy consumption is reduced, but temperature adjustment function may be influenced
Solution Approach 1:
The control device continuously detects the intake temperature and exhaust temperature, comparing these values against target temperatures. Based on this feedback comparison, the control device intelligently decides whether to stop or reduce compressor speed. When detected temperatures meet target conditions, the compressor is stopped or reduced to low speed; when temperatures deviate from targets, the compressor resumes normal operation, ensuring temperature adjustment function is maintained while reducing energy consumption
3Measurement precision
If temperature monitoring points are increased to improve control precision, then control precision is improved, but device complexity increases
Solution Approach 1:
The control device strategically places temperature sensors at specific critical locations: the intake section and the exhaust section of the temperature adjustment device. By monitoring temperatures at these key points where temperature changes most significantly occur, the system achieves effective control precision without requiring sensors throughout the entire system, thus avoiding excessive complexity while maintaining adequate measurement precision for energy-saving control decisions

AI summary
An air conditioning apparatus, which is a temperature adjustment device, is provided with an intake temperature sensor disposed at an intake section of an indoor unit to detect a temperature of gas taken in, and an exhaust temperature sensor disposed at an exhaust section to detect a temperature of gas discharged. After a predetermined time has elapsed since the air conditioning apparatus started operating, when a detected temperature by the intake temperature sensor becomes a predetermined first target temperature or less, a first control signal is output to a control section of the indoor unit to cause the control section to stop operation of the compressor. Subsequently, when a detected temperature by the exhaust temperature sensor becomes a second target temperature or more, the output of the first control signal to the control section is stopped.
